Can you explain what tyre graining is and how it affects car performance?
Is it different to tyre deg that we hear so much about?
GEOFF HILL, EALING
Hi Geoff. Tyre deg is just short-hand for ‘degradation’ of the tyre’s performance, i.e. how much lap time it loses as it is used. But there can be many reasons for that reduction in performance.
